Bierfilzl Wool Felt Coaster Set
Set of 4 coasters made of heavy duty 5mm thick wool felt. As traditionally used for beer mugs in Bavarian taverns until late 19th century, felt coasters are functional, durable and sure to protect your table. Dimensions: 4" sq.
Not surprising that to this day Bavarians call coasters of all kinds "bierfilzl" (beer felt).
